How about the paladin and cleric is Devoted to that power of Good in the first place? Both classes have an assumption of discipline, reverence (to the God or Force they get their power from) and reliability - they go hand and hand with loyalty and desire to serve.FireLance said:This still doesn't answer the question why the powers of Good would rather be served by a second-rate paladin instead of a first-rate warlock.
If someone doesn't have the discipline or conviction to become a cleric or paladin, how can you trust them to serve you? If they don't have what it takes to be a cleric or a paladin, what do you expect of them? And what traits do they possess that you can't get?
